[0008] Furthermore, a guide block inclined outward and upward is provided on the U-shaped opening side of the fixing member.

[0009] Furthermore, the two ends of the rotating shaft are respectively fixedly connected with an outer handle and an inner handle for driving the landing door lock rod to rotate, the outer handle is located outside the landing door and parallel to the landing door lock rod, and the inner handle is located inside the landing door and perpendicular to the landing door lock rod.

[0010] Furthermore, a second buffer block is provided on the first mounting seat at one side facing the rotation direction of the landing door lock rod.

[0011] Furthermore, a third buffer block is provided on the first mounting seat at the B end of the corresponding floor door lock rod.

[0012] Furthermore, a triangular lock is provided on the outer end face of the floor door corresponding to the first mounting seat, and the triangular lock is rotatably connected to a rotating block. The B end of the electromagnetic lock is provided with a toggle rod which can drive the lock tongue at its A end to unlock. The triangular lock drives the lock tongue of the electromagnetic lock to unlock by rotating the rotating block to push the toggle rod.

[0013] Furthermore, a forced unlocking hole is provided on the inner end surface of the first mounting seat corresponding to the floor door, and the position of the forced unlocking hole corresponds to the toggle rod of the electromagnetic lock.

[0014] Furthermore, a signal line outlet fixing hole is provided on the first mounting seat.

[0015] Compared with the prior art, the beneficial effects of the utility model are: compared with the traditional door latch structure, the utility model is safer and more reliable. Only after the landing door lock rod rotates and falls and closes with the U-shaped fixing part, the locking signal permanent magnetic detector on the landing door lock rod will send a door closing signal, which can avoid the occurrence of safety accidents. Among them, the landing door lock rod can realize the opening of the landing door on both sides inside and outside through the inside and outside handles, which is more convenient to use.

The electromagnetic lock 80 is connected to the floor controller through a signal line, and a signal line outlet fixing hole 11 is provided on the first mounting seat 10.

[0024] Working principle: When in use, start the floor controller, the floor controller gives a door opening signal to control the electromagnetic lock 80 to be powered on and opened, and then the floor door lock rod 40 is driven to rotate through the outer handle 50, so that the floor door lock rod 40 leaves the fixing part 70, and the door can be opened; after the personnel enters the elevator, they turn the inner handle 60 inside to drive the floor door lock rod 40 to rotate and then insert it into the fixing part 70. Only when the floor door lock rod 40 is completely rotated and inserted into the fixing part 70, the locking signal permanent magnet detector 80 will send a door closing signal. After receiving the door closing signal, the floor controller controls the electromagnetic lock 80 to be powered off. At this time, the lock mouth 41 of the floor door lock rod 40 is locked by the lock tongue 81 of the electromagnetic lock 80. During the action of the lock tongue 81, the inclined surface of the lock tongue 81 causes the floor door lock rod 40 to push the lock tongue 81 back and then extend it when it falls, thereby realizing the locked state; when the personnel need to come out, similarly, the floor controller controls the electromagnetic lock 80 to open and turns the inner handle 60 to open the door.
